actually I called aero works yesterday to discuss the fact the wings were hard to get in and out, very tight fit, I was transferred to the tech dept and I was given excellent advice and tips on my plane. I was told to sand the inside of the wing where the tube goes in after listening to my symptoms, I am in a very humid area which can cause the wood to swell, so I sanded the tube inside the wing and the wings go in and out perfectly, some of concerns were probably due to being anxious at buying my first 50cc and the investment I made. Turns out I finally got to fly it today after all our bad weather and it flies like a dream, breaking in new engine also so I had to take it easy, the plane flies at just above idle, very docile for landings and going down line, but was very responsive when I needed it. I was really impressed with how the plane flew IMAC maneuvers at just above idle and a new engine. I will continue to buy aero works and I think they give excellent customer service, so I wouldn't let my earlier complaint dissuade you from buying aero works.
